A generator keeps your business running during prolonged power outages by delivering sustained, dependable electricity to your entire site. Unlike UPS systems, which provide instant short‑term protection, generators supply long‑duration power for hours or days, ensuring operations continue without disruption — no matter how long the mains supply is down.
At Shenton Group, our diesel generators are engineered for performance, resilience and total reliability, integrating seamlessly with UPS and ATS systems to form a complete backup power solution.
Whether you’re protecting a hospital, data centre or manufacturing facility, our generator solutions are built to keep your critical operations powered, compliant and productive — whatever happens.
A UPS ensures your business stays operational during power interruptions by instantly delivering backup electricity to critical systems. Unlike generators, UPS systems prevent downtime and protect sensitive equipment from damage. When mains power fails, even a momentary delay can disrupt critical operations.
At Shenton Group, our UPS systems deliver seamless power continuity, bridging the gap between outage and generator startup, and protecting your infrastructure from costly downtime.
Whether you’re safeguarding a data centre, hospital, or industrial site, our UPS solutions are engineered for certainty.
UPS systems are essential for environments where even milliseconds of power loss can cause data corruption, equipment failure, or operational disruption.
